BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a generic emissive display module thatpossesses uniform hardware and power requirements and is capable ofbeing formed into a seamless display. In particular, the presentinvention relates to a self-regulating, high-intensity lighting modulethat can be packaged for different applications or markets and that iscapable of displaying standard video or of providing standard digitallighting technology in a single module.

2. Discussion of the Related Art

High-intensity light sources, such as incandescent, fluorescent, andhalogen lamps, have been long used in many large-scale applications,such as large public information displays, outdoor stadium displays, andtheatrical lighting systems. Originally, large manually-operatedswitches and dimmers were located near the lamps to control theillumination of many large-scale lighting applications. Later, lampswere remotely operated by use of electronic dimmers that employ a lowvoltage direct current (DC) to control the lamps' high voltage power.Most recently, however, digitally controlled illumination systems havebeen developed in which a network of individual lights is controlled bya central computer controlled console. Such illumination systems arewidely used today in, for example, theatrical lighting systems. In 1986,the U.S. Institute of Theatre Technology (USITT) developed the DMX512protocol as a standard digital interface between dimmers and computercontrol consoles. In the DMX512 protocol, each lamp has a digitaladdress and responds to the digital commands sent on a control cable tothis address. A lamp may possess multiple addresses. For example, acolor changing light may have one address to set the mode of the lamp(on/off/sound activated), another address to select the color, and athird address to set the speed at which the lamp changes the color. TheDMX512 protocol is capable of controlling up to 512 addresses per eachlighting group that is referred to as a “universe.” The DMX512 protocolhas allowed uniformity in programming digital lighting; however; acustom hardware setup that uses a variety of lamps is often created eachtime a lighting system is needed. Often, lamps have different powerrequirements: in some cases, they require external regulation; in othercases, they require high voltage, unregulated power supplies. Thus, whatis needed is a self-regulating, high-intensity lighting module that canbe packaged for different applications or markets, for example, forarchitectural lighting, for retail advertising, or for traditionaltheatrical lighting. Therefore, what is further needed is a genericbuilding block light source that possesses uniform hardware and powerrequirements and is capable of being formed into seamless display.

In a separate area of development, projection systems have long beenused to display large-scale moving pictures. The first commercialapplications of large-scale video displays were limited to large arraysof television monitors. Relatively recent advances in the manufacture oflight emitting diodes (LEDs) have made them an attractive light sourcefor large-scale video displays. Large-scale video displays are now beingused for sports stadiums, race tracks, arenas, coliseums, and concerthalls. Therefore, the market is demanding lighter, cheaper, and largerdisplays that are easy to install, maintain, and disassemble, especiallyfor use in temporary venues; these are market specifications that arenot possible to achieve in the older technologies. Additionally, in manylarge-scale applications, for example, in large concert halls or stadiummusic events, both video and lighting effects are desired. However,different display elements are generally needed for large-scale videoversus large-scale lighting, in order to create the desired effects.Therefore a large-scale system that is capable of generating both videoand digitally controlled lighting is needed.

An example of a system that combines video and digitally controlledlighting system is found in reference to world application WO9931560,entitled, “Digitally controlled illumination methods and systems.” Theapplication WO9931560 details processor-controlled LED lighting system,including kinetic illumination, precision illumination, a “smart” lightbulb, an entertainment lighting system, a power/data protocol, a datadelivery track, lighting components, and sensor/feedback applications.In one embodiment of the invention, the lighting control signal can beembedded in any conventional electronic transmission signal, forexample, music, compact disc, television, videotape, video game,computer network, broadcast, cable, broadband, or other communicationssignal. Therefore, for example, the lighting control signal may beembedded into an entertainment signal, for example, a television signal,so that, when the television signal is processed, a portion of thebandwidth of the television signal can control lighting. For example, inthis embodiment, the color and intensity of room lights, as well asother lighting effects, may be directly controlled through a televisionsignal. Thus, a television signal may instruct the room lights to dim atcertain points during the presentation, to strobe to different colors atother points, and to flash at other points.

However, the invention requires a decoder in order to split the incomingcombined signal into a separate entertainment signal and lightingcontrol signals. Subsequently, a lighting block that is used only forillumination purposes and an entertainment device that can be used onlyto display video process these signals. Therefore, WO9931560 is limited,in that it requires the use of separate modules for video display orlighting. Thus, what is needed is a device capable of providing bothstandard video and standard digital lighting technology in a singlemodule.

DESCRIPTION OF THE PREFERED EMBODIMENT

The present invention relates to a generic lighting module thatpossesses uniform hardware and power requirements and is capable ofbeing formed into seamless display. In particular, the present inventionrelates to a self-regulating, high-intensity lighting module that can bepackaged for different applications or markets and is capable ofdisplaying standard video or providing standard digital lightingtechnology in a single module.

FIG. 1 illustrates a functional block diagram of intelligent lightingmodule 100 in accordance with the invention. Intelligent lighting module100 includes an input for power 110, an input for serial data 112, aninput for communications data (comm data) 114, a control board 120, anda display board 130. Control board 120 further includes a regulation 122for power, a memory 124, a display logic 126, and a display buffer 128.Display board 130 further includes a drive buffer 132, an array ofdrivers 134, an array of lighting elements 136, and a sensor 138.

Input for power 110 is a standard, unregulated or regulated power supplyfor intelligent lighting module 100, in the present example, +48V DC.However, other implementations of power 110 are possible and include AC,for example, 110V AC or 220V AC.

Serial data 112 contains the display image data, for example of a videosource, which comprise for example the pixel location address, and thevalue for the red, green, and blue (RGB) components of the pixel color;however, numerous other color definitions and standards are possible forserial data 112. Serial data 112 is updated according to the displayrefresh rate, as is well known to those skilled in the art.

Communications data 114 is a digital serial input, for example of alighting console, with for example DMX512 protocol data, as is wellknown to those skilled in the art that controls digital lightingeffects, such as switching, dimming, and fading. Other communicationprotocols are possible, including custom lighting protocols. For furtherinformation regarding a custom lighting protocol, we refer to anotherprovisional application in the name of the same applicant, entitled,“System for and method of providing a common protocol for lighting andvideo devices.”

Control board 120 provides all the power regulation, processingcapabilities, digital memory, and electronic buffering functions forintelligent lighting module 100.

Regulation 122 provides all the power conversion and regulationfunctions required to produce internal source of power for all theelectronic devices of intelligent lighting module 100. Memory 124 withincontrol board 120 includes standard electronic components, such as“programmable read-only memory” (PROM) and “random access memory” (RAM).The content of Memory 124 contains such data as hardware configurationcode, executable code, look-up tables, display data, ambientenvironmental data, and the installation controller. The installationcontroller contains data for the unique installation parameters ofintelligent lighting module 100 that affect the operation of intelligentlighting module 100 such as the height of the module in the large-scaledisplay, the module orientation, and the module viewing angle. Displaylogic 126 includes standard electronic components, for example, a fieldprogrammable gate array (FPGA). Display logic 126 provides all thedigital processing capabilities necessary for the correct operation ofintelligent lighting module 100. Display buffer 128 includes commonelectronic components, such as tri-state latches, tri-state linedrivers, and electronic filtering components, such as capacitors (notshown).

Display board 130 provides the display lighting and the supportfunctions necessary for its operation. Drive buffer 132 input paralleldata from control board 120 and decode and latch the lighting data.Drivers 134 include the standard display drivers necessary to illuminatelighting elements 136, and are, for example, constant current driversthat are commonly used for light emitting device (LED) displays orconstant voltage drivers, used for liquid crystal displays (LCDs).Lighting elements 136 contain an array of individual pixel elements (notshown) that comprise the display, for example, an array of inorganic ororganic light emitting diodes (LEDs or OLEDs) or an LCD. Sensor 138monitors the internal environmental conditions of intelligent lightingmodule 100, for example light and temperature, for display intensityprocessing by control board 120.

In operation, intelligent lighting module 100 receives pixel image dataon serial data 112, display control data on communications data 114, anddisplay power on power 110. Power 110 and communications data 114 mayoriginate, for example, from a controller (not shown). Further to thisexample, serial data 112 may originate from this controller or fromanother intelligent lighting module 100. Display logic 126 inputs serialdata 112 and then “deserializes” it in order to produce parallel pixeldata. Serial data 112 may not be transmitted in the order of thesequential pixel addresses; therefore, display logic 126 reorders theparallel pixel data and stores it in memory 124 in the order ofsequential pixel addresses. Further, the order of sequential addresslocations in memory 124 may not be in an order that corresponds to thesequential pixel locations of lighting elements 136. Therefore, todisplay an image, display logic 126 determines a display drive orderfrom a look-up table stored in memory 124 that is uploaded viacommunications data 114 upon power-up.

Display logic 126 then latches the parallel pixel data that correspondto contiguous pixel locations onto drive buffer 132. Drivers 134 thenilluminate the corresponding pixels of lighting elements 136 to producea single image at the display rate.

FIGS. 2A and 2B illustrate front and rear perspective views,respectively, of an intelligent lighting module assembly 200.Intelligent lighting module assembly 200 is suitable for use as anautonomous display, or, alternatively, may operate within a set ofintelligent lighting module assemblies 200 to form a larger display (notshown). Intelligent lighting module assembly 200 is, for example, an8×11 planar matrix assembly of emissive lighting elements 210. Alarge-scale display (not shown), is formed of a plurality of intelligentlighting module assemblies 200 to create, for example, a display thatcovers an entire wall. For further information regarding large-scaledisplays, we refer to the description in the present provisionalapplication, entitled, “Improved display and corresponding support,emissive lighting display modules Mechanical packaging and supportframeworks for lighting modules and packaging for such display modules.”

In operation, a plurality of lighting module assemblies 200 areinterconnected to form an overall large-scale display (not shown) thatis operated, for example, by means of a display controller (not shown).

FIG. 3 illustrates an exploded rear view of intelligent lighting moduleassembly 200 in accordance with the invention. Intelligent lightingmodule assembly 200 includes a front optics 310, a display boardassembly 314 that includes a mechanical interface for attachment offront optics 310, a control board assembly 316, a chassis 318, a heatsink 324, a cooling fan 320, a fixation interface 328, a fan cover 322,and bolts 312. Cable connector 326 is part of the cable (not shown inFIG. 3) and is connected to the connector on the control board assembly316.

Front optics 310 is a protective lens cover for intelligent lightingmodule assembly 200. Front optics 310 encases, for example, an 8×11planar matrix assembly of emissive lighting elements 210; however, frontoptics 310 is not limited to the present example and may accommodate avariety of geometries and hold various numbers of emissive lightingelements 210 for different applications. Further, the lens design offront optics 310 determines the optical quality of emissive lightingelements 210; for example, front optics 310 that possess a smallemissive cone provide a greater fill factor and result in a betterquality video display. Additionally, front optics 310 may be replacedduring the lifetime of intelligent lighting module assembly 200, eitherto maintain the display because of normal wear or damage or to upgradeintelligent lighting module assembly 200 to change the style orperformance of the display. For further information regarding opticaldesigns for lighting module assembly 200, we refer to the description inthe present provisional application entitled, “System for and method ofoptically enhancing video and light elements.” A mechanical interface(not shown) that includes a structural frame affixes display boardassembly 314 and chassis 318 to front optics 310. Display board assembly314 contains emissive lighting elements 210 and electronic displaydrivers, as described in the discussion of display board 130 inreference to FIG. 1. Display board assembly 314 also provides a mountingstructure for control board assembly 316. Control board assembly 316contains all the intelligence required in order to operate the displayfrom a standard data source that includes control data, i.e., DMX512,and serial display data, i.e., RGB data, as described in the discussionof control board 120 in reference to FIG. 1. Control board assembly 316contains the power regulation capabilities to power the display.Therefore, intelligent lighting module assembly 200 is a lightingelement that converges standard video and standard digital lightingtechnology in a single module. Chassis 318 is the chassis of intelligentlighting module assembly 200 and the physical interface to a mountingstructure (not shown). Fan cover 322 holds cooling fan 320 in place onthe rear of chassis 318. Fixation interface 328 is the mechanicalinterface needed to attach the fan cover to the chassis 318, by means ofbolts 312. Chassis 318 can be modified to accomplish different packaginggeometries; therefore, intelligent lighting module assembly 200 is aself-regulating, high-intensity lighting module that can be packaged fordifferent applications or markets. Heat sink 324 is incorporated in thedesign for the thermal cooling of the control board assembly 316 and thedisplay board assembly 314.

In operation, control board assembly 316 receives serial display data,display control data, and power from a source, for example, a displaycontroller (not shown), by means of cables (not shown) that connect tocable connector 326, and processes these inputs to activate and modulatethe illumination of intelligent lighting module assembly 200 thatcreates a display or a portion of an overall display. A large-scaledisplay is constructed from an array of intelligent lighting moduleassemblies 200, for example, a large-scale wall display (not shown).

FIG. 4 illustrates a block diagram of an intelligent lighting modulesystem 400 in accordance with the invention. Intelligent lighting modulesystem 400 includes, for example, a plurality of intelligent lightingmodule assemblies 200 a, 200 b . . . , 200 n, an interconnect 410, avideo source 412, a lighting console 414, a lighting controller 416, andoptionally, an ambient environmental controller (AEC) 418. Intelligentlighting module system 400 is not limited to the implementation of thecurrent example; therefore, other lighting system architectures thatutilize intelligent lighting module assembly 200 are possible. Forfurther information regarding other lighting system architectures thatutilize intelligent lighting module assembly 200, see anotherprovisional application in the name of the same applicant, entitled“System for and method of providing a common protocol for lighting andvideo devices.”

Interconnect 410 is a cable that has multiple conductors and thatcarries power 110, serial data 112, and communications data 114 to eachintelligent lighting module assembly 200 in intelligent lighting modulesystem 400. Video source 412 is a video transmission device, forexample, a personal computer display input or a video processor displayinput, that provides a video feed, for example, SDI or RGB, to lightingcontroller 416. Lighting console 414 is a computer console that runs theapplication software used to control and operate intelligent lightingmodule system 400, in order to produce a variety of lighting effects,for example, brightness, dimming, color changes, and video effects.Lighting console 414 is widely used in, for example, theatrical lightingsystems. Lighting controller 416 is a device that provides serialdisplay data and control data directly to intelligent lighting moduleassemblies 200. Lighting console 414 communicates to lighting controller416 via control data protocol, i.e., DMX512 protocol. Optionally,ambient environmental controller 418 provides ambient environmentaldata, including for example, ambient temperature, illumination, andhumidity via communications data 114, to intelligent lighting moduleassemblies 200. In operation, lighting controller 416 receives a videofeed from video source 412 and control data, i.e., DMX512 protocol, fromlighting console 414 and outputs serial display data and control data toeach intelligent lighting module assemblies 200 via interconnect 410.Intelligent lighting module assemblies 200 receive serial display dataand control data, including module installation parameters, such as theheight of the module in the large-scale display, the module orientation,and the module viewing angle from lighting controller 416 viainterconnect 410. In addition and optionally, intelligent lightingmodule assemblies 200 receive ambient environmental data, from ambientenvironmental controller 418, via interconnect 410. Each intelligentlighting module assembly 200 uses these signals to illuminate in anarray that forms an overall display. A large-scale display isconstructed from an array of intelligent lighting module assemblies 200,for example, a large-scale wall display. Therefore, intelligent lightingmodule assemblies 200 function as a generic building block light sourcethat possesses uniform hardware and power requirements and is capable ofbeing formed into seamless display.

FIG. 5 is a flow diagram of a method 500 of using an intelligentlighting module assembly 200 in accordance with the invention. Method500 includes initial assembly, and automatic configuration ofintelligent lighting module system 400 and FIGS. 1 through 4 arereferenced throughout the steps of method 500. Method 500 includes thefollowing steps:

Step 510: Defining Display System

In this step, the system parameters for a display application aredefined for intelligent lighting module assembly 200, according to theneeds and specifications of the overall display system (not shown).System parameters include, for example, the number of intelligentlighting module assemblies 200 and addresses for each, the supportframework (not shown), the mechanical interface to the supportframework, and front optics 310. Method 500 proceeds to step 512.

Step 512: Assembling Components

In this step, the components of the system are prepared forinstallation. For example, front optics 310 is assembled intointelligent lighting module assemblies 200. Method 500 proceeds to step514.

Step 514: Assembling Display System

In this step, the components of the system are installed in the displaysystem. For example, intelligent lighting module assemblies 200 areassembled into the support framework of the display system. Method 500proceeds to step 516.

Step 516: Linking Display System Components

In this step, intelligent lighting module assemblies 200 areinterconnected to each other, in order to provide power, video, and datacommunication, e.g., by a local area network (LAN) or by a DMX512,throughout the entire display system. Method 500 proceeds to step 518.

Step 518: Linking Communications Data

In this step, interconnect 410 is linked to lighting controller 416 inorder to provide a source for power, video, and data communication,e.g., LAN or DMX512, to the interconnected display system. Method 500proceeds to step 520.

Step 520: Auto-Configuring

In this step, intelligent lighting module assemblies 200 areauto-addressed, auto-positioned, and configured, so that they cangenerate the lighting required by the system application. Lightingconsole 414, for example, detects the number of intelligent lightingmodule assemblies 200 which are contained in the display system andsends the appropriate control information including module installationparameters, such as the height of the module in the large-scale display,the module orientation, and the module viewing angle, to intelligentlighting module assemblies 200 via controller 416 and interconnect 410,so that the modules are individually capable of displaying theappropriate information. Further to the example, intelligent lightingmodule assemblies 200 have enough intelligence to alter the incomingdata, i.e., to compensate for ambient temperature; however, the DMX512data stream on interconnect 410 is not altered. Method 500 ends.
